Abstract: A safety device (61) for a lighting valve (23) of a gas burner, comprising a starting button (36), a return spring (57), a cutoff shutter (42) controlled by the starting button (36), a control shutter (41) for a pilot light nozzle, and a holding electromagnet (54) for the control shutter (41). The control shutter (41) is normally closed and is actuatable through the starting button (36) for the flowing of the gas to the pilot light nozzle, whilst the holding electromagnet (54) is dependent on the pilot light to hold open the control shutter (41). The starting button (36) is provided for rotation and can be depressed only for a given angular start position so that, for starting the lighting, the button (36) must be rotated up to said start position and subsequently depressed to close the cutoff shutter (42) and open the control shutter (41).
